Think this is one of my favorites all around NG, its so natural in every aspect I look at it, feels really alive, don't know if you used a real-life reference or not but it seemms like that, theres an entire personality wroten on the lines of this one, congratulations.

This is incredible work! Your attention to detail is meticulous. It kind of scares me to think of all that cross-hatching. o.o;;; I also love the slight splash of muted colors. Overall excellence. Bravo. =]
